Question:
The proportion of which of the following volatile fatty acid is higher in the rumen of animals fed on fibrous diet?
The proportion of which of the following volatile fatty acid is higher in the rumen of animals fed on fibrous diet?
Show Hint
Fibrous diet: more acetic acid.
Concentrate diet: more propionic acid.
VFAs: acetate, propionate, butyrate.
Concentrate diet: more propionic acid.
VFAs: acetate, propionate, butyrate.

- Butyric acid
- Acetic acid
- Propionic acid
- Valeric acid
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Rumen fermentation produces volatile fatty acids (VFAs).
The proportion of VFAs depends on the diet.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the VFA profile in ruminants.
Step 3: Detailed Explanation:
In animals fed on fibrous diets, the proportion of acetic acid is higher.
Fibrous diets promote acetate production.
Concentrate diets promote propionate production.
Butyrate is produced in moderate amounts.
Thus, acetic acid is higher in fibrous diets.
Step 4: Final Answer:
Acetic acid is higher in the rumen of animals fed on fibrous diet.
Hence, the correct option is (B).
Rumen fermentation produces volatile fatty acids (VFAs).
